The Jetta GLI is powered by a 2.0-liter turbocharged direct-injection TSI four-cylinder engine that delivers 228 horsepower and 258 pound-feet of torque. Sometimes referred to as a "VW GTI with a trunk," its mission is simple: to deliver a German performance sedan at an affordable price. The Volkswagen Jetta GLI is a higher performance version of the brand's popular compact sedan. The headlights have also been darkened, and the rocker panel has been redesigned. The updated rear bumper has honeycomb air outlets, oval exhaust pipes, and a new rear diffuser. Updates to the 2020 R8 include an updated front bumper with a new honeycomb grille with R8 badge, front spoiler lip, and lateral air intakes. Audi says the car's top track speed is 201 mph. Able to draw on 30 more horsepower than the previous year's model, the powertrain allows the slippery coupe to jet from zero to 60 mph in 3.4 seconds. For 2020, the naturally aspirated 5.2-liter FSI V-10 engine in R8 V10 Coupe produces 562 horsepower, and that prodigious horsepower is delivered by a seven-speed S tronic dual-clutch transmission, which can shift gears in as little as 120 milliseconds. Enthusiasts around the world agree and applaud the model's ever-increasing performance. When the system senses the need, however, the rear wheels are engaged in fractions of a second via the center differential, activated by an electro-hydraulic oil pump.Īudi says its mid-engine R8 sports car is the pinnacle of performance for Audi, with no other model bearing a closer tie to racing. When operating under a relatively low load or when coasting, only the front wheels are driven and the rear wheels are decoupled, helping to save fuel. All Golf R models are equipped with Volkswagen’s 4Motion all-wheel drive. Golf R models with the DSG automatic also feature a stop-start system designed to help save fuel when the engine would otherwise be idling needlessly. To optimize its performance, VW offers the model with a seven-speed DSG dual-clutch transmission very similar to the Audi’s. (VW suspended production of the Golf R for the 2020 model year, but it’s expected to return in the near future 2019 inventory remains plentiful as of this writing.) The R features one of the most powerful four-cylinder production engines in the world: the same turbocharged, direct-injection TSI 2.0-liter engine as the Audi S3, producing 288 horsepower and 280 lb-ft of torque. The 2019 Volkswagen Golf R is the most powerful version of the brand's popular four-door hatchback. For ease in everyday driving, a "gliding" function can be selected in the "Individual" driving mode. Thanks to AMG Dynamic Select driving mode, a feature of the DCT, each driver receives a specific drive configuration with different accelerator and gearshift characteristics based on how they drive. The transmission's gear ratios have been configured so that the driver experiences very "spontaneous acceleration" in all speed ranges, combined with fast-shifting, optimum connections when shifting up through the gears and automatic double de-clutching when shifting down. It is powered by a 382-horsepower 2.0-liter engine that Mercedes calls the world's most powerful turbocharged four-cylinder manufactured for series production, accompanied by the AMG Speedshift DCT-8G dual-clutch transmission with eight gears. As you would guess from its Mercedes-AMG designation, the CLA 45 is performance-oriented in the extreme. The recently redesigned Mercedes-AMG CLA 45, the performance sub-brand's four-door compact sports coupe, is one of the latest cars to feature a dual-clutch automatic transmission. At the same time, some DCTs shifts can feel abrupt and harsh in everyday driving, prompting many car manufacturers to use different technology. Shifts typically are completed much faster than with a manual gearbox. As each gear is engaged to drive the vehicle, the next higher numerical gear is pre-selected so that it can be engaged virtually instantaneously when the transmission’s automatic logic or the driver’s manual selection chooses it. The twin transmissions are joined with two clutches, and they work in tandem. Each DCT is essentially was two separate transmissions, one providing the odd-numbered speeds (first gear, third gear, fifth gear) and the other providing even-numbered speeds. The major advantage of the dual-clutch transmission is its ability to execute extremely rapid gear changes. While a few major manufacturers continue to be major proponents of the technology, others either failed to adopt it or have moved on to more highly developed conventional torque-converter-based automatics and continuously variable transmissions of various types. Once regarded as the best solution for automatic gear-shifting in performance cars, the dual-clutch transmission (DCT) has begun to slip from favor. 2014 CLA CLASS COUPE ・ Photo by Mercedes-Benz
